I believe the track has been upgraded to 30 mph for passenger trains, yes it will be a long slow trip compared to our 70 and 80 mph running, but like CRail said, many passengers would rather sit back in relax on a train than sit on Route 3 and Route 6 for 3 hours. No thank you..... also the grade crossings, almost all have been upgraded with lights and gates. I'll get more detailed answers from an engineer that worked for Mass Coastal and report here. this line has been quietly rebuilt over the last few years
